) – TOM
2)
N.A. ACPI reclaim, MPS and NVS area
3)
(TOM - FB - TSEG
4)
) – (TOM - FB) N.A. VGA frame buffer
5)
1024 kB – (TOM - 8 MB - 192 kB) 100000h - N.A. Extended memory
869 kB – 1024 kB 0E0000h - 0FFFFFh Runtime BIOS
832 kB – 869 kB 0D0000h - 0DFFFFh Upper memory
640 kB – 832 kB 0A0000h - 0CFFFFh Video memory and BIOS
639 kB – 640 kB 09FC00h - 09FFFFh Extended BIOS data
0 – 639 kB 000000h - 09FC00h Conventional memory
Table 122: RAM address assignment
1) FB - VGA frame buffer
2) TOM - Top of memory: max. installed DRAM
3) Only if ACPI Aware OS is set to "YES" in the setup.
4) TSEG - Intended internally for SMI handling in system BIOS.
5) The VGA frame buffer can be reduced to 1 MB in the setup.
1.11.2 I/O address assignment
I/O address Resource
0000h - 00FFh Motherboard resources
01F0h - 01F7h Primary IDE channel
03B0h - 03DFh Video system
03F6h - 03F6h Primary IDE channel command port
03F7h - 03F7h Primary IDE channel status port
03F8h - 03FFh COM1
0480h - 04BFh Motherboard resources
04D0h - 04D1h Motherboard resources
0800h - 087Fh Motherboard resources
0CF8h - 0CFBh PCI config address register
0CFCh - 0CFFh PCI config data register
0D00h - FFFFh PCI / PCI Express bus
1)
4100h - 417Fh MTCX
FF00h - FF07h IDE bus master register
Table 123: I/O address assignment
1) The BIOS assigns the PCI and PCI Express Bus I/O resources from FFF0h downward. Devices that are not compatible with PnP/PCI/
PCI Express cannot use the I/O resources in this area.
